Light sensors often use an infrared LED as a light source. Infrared LEDs have a greater intensity than LEDs that emit visible light. And when infrared photodiodes are used the sensors are relatively ...

Photoelectric sensors and light curtain sensors are among the most commonly used sensing devices in factories. Photoelectric sensors are mainly used to detect parts products or material movement.

The sensors can be used for material handling on conveyors, AS/RS applications, order fulfillment, and in similar applications. The light grids come in standard and programmable models. Standard ...
